RediStair® is a concrete product that can bring the value of a concrete stair to a building owner at a cost competitive with steel stair systems. The advantages of concrete stairs over steel are many; they are more durable, quiet, solid, and more architecturally appealing than steel or steel frame with concrete tread systems. The tradeoff has always been the cost to upgrade from steel to concrete; RediStair® is the solution to this problem.
